T 0]] whom it may concern:

Be it known that I, GEORGE E. CorrRELL, a citizen of tllBUIlltGd States, residing at Tottenville, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Garbage- Incinerating Apparatus, of which the follow-v ing is a specification.

This invention relates to furnaces for incinerating garbage and refuse, destroying the noxious vapors and'odors arising therefrom, and utilizing the gas and "other valu- .Is in divided portions or charges on separate gratesoneabove another in my improved able byroducts.

The 0 ject of my invention to provide for e'tl'ectlvely treating garbage and refuse furnace, for readily dumping each charge when at the properstage of treatment tothe gratebelow, and agitating the garbage to prevent it from becoming impacted until it is completely incinerated. Y I In the effort heretofore made to burn garbage on grates or shelves one above an other the garbage would remain moist, sticky, and impacted against the 'i'urnace wall, adhering to the latter, so that the grate could not be rotated for dumping its charge wvitho'ut much loss of time and waste of heat.v

By my improved construction and operation these dilliculties are overcome and in'lproved results secured. I

I inject jetsoi" combustible gas or hydrocarbon vapor and currents of hot air around the circumferential edges of the grate or wall of the furnace, producing circles of flame adjacent to the furnace-walls, so that the circumferential edges of the diilerent layers or charges of garbage on the grates are first dried and burn'edaway, thus permitting the grates to be readily rotated and the charge dum' ed-to'the grate below.

I am thus enable to keep the charges agitated and loose,

so as to be readily permeated by currents of hot air and flame, thereby greatly facilitating the drying and incinerating operations. The walls of the i'ncinerating-chamber are made flaring from the ashpit to the top like an inverted cone, so that the largestgrate area will be a't'the top, where thelresh moist garbage may be spread out in the thinnest ayer to facilitate drying.

As the charges I become dried and reduced by incineration they aredumped onto grates of successively vsm'aller'area, where combustion and reduction proceed more and more rapidly till the incin eration is completed. By this construction the furnace may be worked to its full capaci'ty and all heat units utilized, resulting in a.

great saving of fuel.

Another object. of my invention is to provide for storing garbagein tight hoppers, or

other suitable receptacles on wharf, col .lecting the same by means of a boat containing the incinerating apparatus and as the garbage is discharged from the hop er squeezing out-the water, then assorting 1t yhand to remove and separately store tin cans, metal,

glass, rubber, &c and at the same timeexhaust all odorous gases into the furnace, so as to insure satisfactory sanitary conditions. In this operat on an a1r-tight flexible'hood is stretched over the squeezing-rollers and conveying-belt, so that the odor shall not escape, and an exhaust-tan is used for drawing the o'dorous vapors into the escape-flue of the furnace. By gathering the garbage and trea"- ing it on a boat, as can be done in many large cities, the long and expensive haul or transportation by land is avoided and de-' cidedly economical results secured. The length of time required for storage and treatment of the garbage is also much shortened, and thus danger arising from long exposure of the garbage to fermentation is overcomev Another object of m invention is to provide for cond ensing or concentrating the odorous vapors and particles of ash and carbon drawn oil from. the incinerating-i'urnace and utilizing the same as liquid fertilizer;

gases to convert them into illuminatinggas,

and thus utilize all the valuable byproducts.

The grease and tarry matter are also drawn.

off from the condensing-tank for-separate in will be set forth inthe claims}- also, to provide tor treating the uncondensed' I to in- I will now describe the details of construe:

tion-and operation of my improved incinei ating-furnace and condensing apparatus by reference to the accompanying drawings, in

which Figure 1 represents'a vertical longitudinal sectionalview of the garbage'and refuse funnaces and part of the condensing apparatus. Fig. 2 represents a verticalsectional elevabers B B will become very highly heated by the circles of flame, which would be destructive to brick, causing partial fusion thereof and adhesion of ash and carbon, I provide iron water-jackets a. for such chambers. The chargeof garbage therefore as dumped from 71 one grate to the other will slide freelydown l the inclined wall to the grate below. The burner-pipes f are preferably passed through 1 openings f as shown in Fig. 8. The jour r al-boxes b are preferably made of cast metal in upper and-lower halves and provided with extension-plates containing the openings f Inclined shields b are secured to the inner ends of the journal-boxes for protecting' the journals and preventing ashes or refusefrom entering the boxes, as shown on enlarged scale in Figs. 8 and 9.

The gas and vapor flue D'is preferably made large and secured to the top of the fur naces A A, as'shown in Figs. 1 and 3, and are provided at the sides with openings d, to

which are fitted the slidin doors'w. Any

suitable means may be use for fastening the. The flue D is doors ti ht upon their seats. provide near the top with two or more up 'cujlar openings d, fitted with short'inlet-pipes containing the fans T, mounted u on stands t. The fans T may be, operated y electric or other power and serve for drawing noxious ases orvapors from the spaces below the ood U-and dischar e them into the flue D..

The flue D connects the downtake-flue D witha condensing-tankfi,which is rovided valve 9'', "as shown 111 Fig. 2.

at the bottom with a' drain-pipe g, a'ving a For the purpose of producing. a strong exhaust draft from the incinerating-furnaces I provide Waten-sprays discharging in the, 'downtakeflue ,D.

An endless-chain pump H, having suitable 'whe'els and endless chains provided with 3 and also servefor condensin causing precipitation of all ash buckets g, is suitably mounted above tank G, as shown in Figl l. Pipes h h are provided for the endless chains and buckets and are secured to the top plate of the tank. Perforated pipes h connect with said pipes -7l, and pass in a U shape down into the tank,

so as to be submerged in a liquid, as shown'in Fi 1. I w T ischargepipes having perforated nozzles or rose-heads h connect with the upper ends of the pipe h and deliver strong sprays or jets. ofwater into the downtake flue D. These sprays of water produce a strong draft 0 vapors and and carbon which are drawn off from the incineratingfurnaces. The liquor in'ta'nk G- is pumped over and over again until it becomes highly charged with products of cbndensation, formi'ng a liquid fertilizer. y from time to time through the drain-pipe g, and fresh water is supplied as required irom This is drawn off any convenient source. The liquor in tank G becomes highly heated to a boiling temperature, and the matter not condensed at such temperature is drawn off through a dis.-

charge-pipe I, which connects with the-top'of tank G, as shown in Fig. 2. Pipes I 1 form a continuation of pipe 1 and connect with the second condensing-tank K.- The downtakepipe I may be supplied with some form of orous material to serve as a wet scrubber or the gases which are passed through it. The water supply pipe H passes down through the top of pipe I and terminates in a rose-head h for su plying fresh water to condensev and purify tl ie gas. In the pipe or fine I, I construct a centrifugal flame-burner which is composed of-inclined burner-pipes f, connecting with the and 5, and of a flaring spreader and air-inlet L." An air-supply pipe C, having'a valvec, connects with the lower end of the conical spreader L. Air is discharged from the upper flaring end of the cone L for causing comustion of noxious gases which pass up through the flue I. a

The inclined burner-pipes f produce a solid centrifugalfiame around the cone L, and the noxious gases which pass from tank circular supply-pipe-I, as shown in Figs. 2; I i

G ere caught by the circulating flame and I consumed. The gaseous products which pass off from this burner are mostly fixed gases, and they may be passed off through the pipe lc to the ash-pit of the furnaces A A or to any other place of use. These gases may also be passed off through the pipe ]c into return-pipes in the retort-furnace M.

The pipe 76 may be continued backward and forward through the furnaceM and connect by a return-bend 'm at the front with the oil retort The gases are thus highly holder 0. This holder is provided with the usual water-tankO and with an outlet-pipe '0 for conducting gas to anydesired place of use. The gas may be used as a heating agent for steannboilers or as a motive power in gasengines. This apparatus for earbureting and fixing the waste gases is used in co'nnec lion with the incinerating apparatus'whenit is'loca'ted on land, but could also be used on a boat when'desired. A force-pump l maybe used for drawing oil from an underground tank to supply the pressure tank N. A

Iio

small air-pump n is used for forcing air into tankN above the'oil for forcing oil through pipe at to'the retort.

T; furnace A is intended for burning refuse material which is. comparatively dry and which'does not require so large a grate-surface as the, moist garbage which isevapouse-chamber B will be fed from a separate rated and burned in the furnace A. The refchute or platform and may be used for burning sawdustgchips, shavings, and other combustible refuse matter. I

By my method of collecting garbage and water-front of many large cities, the garbage able manner. Sanitary conditions are thus' and other refuse can be conveniently hauled a comparatively short distance and stored in hoppers or bins on wharves and discharged therefrom into the boat. When desired, a

large quantity of-garba'ge may be discharged at one time into a hopper or bin on the" boat, which can. then be propelled out on the river or bay, during which time the garbage may be treated as above described. The operation of treating the garbage can thus be actively conducted while the boat is passing from-one wharf. or station to another. The

destruction of the garbage and gases is thus effected in the least oflensive and ob ect10n perfectly maintained, and the work of treating the garbage is economically conducted.

It is tovbe noted that in my method all the T e highly-heated Prachill from the garbage-incinerating apparatus.
